Cygwin: termios: Change argument of fhandler_termios::spawn_worker()

This patch changes the argument for passsing a path to an app
to fhandler_termios::spawn_worker() from const WCHAR *runpath
to path_conv &pc. The purpose of this patch is to prepare for
a subsequent patch, that is intended to fix a bug in executing
Microsoft Store apps.
